LONG ISLAND CITY, NEW YORK, ASSIGNOR'TO CONE CO EvIPANY OF AMERICA, OF LONG ISLAND CITY, NEW YORK, A CQRPORATION 0F DELAWARE,

APPARATUS ron, THE MANUFACTURE or Ion-cumin corms.

Application filed April 1-7, 1922, Serial No. 553,766. Renewed March 27, 1925.

T 0 all whom it may concern:

Be it known that I, HARRY L. BOWDOIN, a citizen of the United States, residing at Long Island City, in the county of Queens and State of New York, have invented certain new and useful Improvements in Apparatus for the Manufacture of Ice-Cream Cones, of which the following is a full, clear, and exact specification, reference being had to the accompanying drawing, which forms part of the specification. 7

This invention relates to apparatus for cause the latter may contain an excess of batter, or perhaps parts of an undischarged cone, in addition to anew quota of cone forming material, will be thereby cocked up to lie in the path of the upper, pendent burners, so that in passage of the moulds through the heating zone, the cooked up core carriers will strike the burners and break them off.

Therefore my invention comprises the employment of guard means located between the support for the upper burners and a projecting portion of the core carrier, with an inclined approach which permits the core carrier, when raised, to glide upwardly beneath the guard means, thereby bodily lifting the burner support to clear the burners from the core carriers, in order that the latter may continue their course without damage to the burners.

I also provide signalling means to indicate to an attendant the fact that a core carrier is not properly closed upon its mould, so that he may remedy the trouble.

Other features and advantages of my invention will hereinafter appear.

In the drawing Figure 1 is a partial, plan view of an apparatus embodying my invention, showing the gas pipes which constitute. the burner supports, and guard means in the form of a segmental rail.

Fig. 2 is a section, on an enlarged scale, on the line 22 of Figure 1.

Fig. 3 is a side elevation, partly in sec tion of Fig. 2. r

Fig. 4 is a side elevation of the apparatus sluziwing; a trip device to actuate the signal, an

ling means. v i r r In the drawing Ihave considered it nece s- V sary to show only such parts as are assooi ated for the performance of my invention, because the general character of an apparatus with which my improvement is to be used is illustrated in Patent No. 1,289,209,

Therefore, in said: figures, let 1- indicate a series of gaspipes, centeringly arranged, and supplied by a main pipe 2, from which they supportingly project in a horizontal plane. These pipes 1 are shown as having each a pair of burners 3 pendent therefrom, in longitudinally spaced relation along said pipes; and as having secured thereto, as by straps 4', an arcuate rail 5, comprising a guard, which depends below the pipes 1', intermediate the respective burners of thepairs thereof. a 1

The rotary carrier '6', shown in Patent 1,289,209, carries the mould units Whichinclude the mould sections 7 and pivotal arms 8 that carry the core cover portions 9 with cores 10, the core covers being adapted to swing open to permit batter to be introduced intothe moul'd'sections, and then to swing close down upon said sections for cone forming and baking purposes.

Fig. 5 is an end View showing the signal- \Vhen themoulds have been charged and I the covers closed, then, in the rotation of carrier 6 the moulds are passed through'the heating zone, which, see Patent No. 1,289,209, is equipped with upper and lower burners.

Since it is with the upper burners 3 that this invention is particularly concerned, it should be noted that it is desirable to pass the mould covers as closely as possible to said burners in order to receive the full benefit of the heat therefrom, the clearance being so slight that if the. covers 9 are not snugly closed they are liable to strike against the burners in their travel, as has been premised.

vThe covers 9 are provided each with an upwardly extended rib 11, having a forward end incline 12, this rib being vertically aligned with rail 5 and normally passing under it non-contactingly. But, should a cover 9 be cocked up for the reasons, adduced, then the rib 11, on meeting the rail, will, by means of its incline 12, raise the rail 5 together with the pipes 1 and their burners to a planewhi'ch will leaveample clearance for the cocked up cover 9 to pass freely under the burners, thus entirely avoiding possibility of the cover striking. the burners. Since itis important that notification be given the attendant that a mould cover is not properly closed, I also provide the following means for announcingthe occurrence,

Pivoted as at 13 toa fixed'pa'rt of the ap paratus adjacent to the burners 1s a s-emaphore 14 which carries a distinguishing signal l5; and, pivoted to a bracket 16 that is extended also from a fixed partaof the apparatus is an arm 17, whose upper end is provided with a latch 18,'that normally engages the semaphore 1 1 to hold it in a depressed position, against the tension of V a spring 19 that tends to throw it upwardly.

The lower end of arm.17 is inclined, and

lies in the path of cover 9 in the movement of the mould when the cover 9 is raised through non-closure; Therefore, under these circumstances, with the actuation of rail 5 to raise the burners, the arm 17 will be tripped by cover 9 to release its catch engagement with the semaphore, permitting" the latter to spring. up and display the alarm signal. 7

Variations within. the spirit and scope of my invention are equally comprehended by the foregoingdisclosure. I I claim I 1. In an apparatus for the manufacture of edible cones, having pendent burners, a

support therefor, and a revoluble, mould carrying member with a mould cover to pass,

while closed, under the burners, the combi nation of means operable by the mould cover,when slightly raised, to elevate the" support and thereby provide a clearance which permits the raised cover to pass'under the burners. a

2. In an apparatus for the manufacture of edible cones, having pendent burners, a

support therefor, and a revoluble member carrying a mould, with mould cover, to pass, when closed, under the burners in contiguity therewith, the combination of an arcuaterail pendently carried by the support for the burners, the mould cover provided with a rib circumferentially aligned with the arcuate rail when the cover is snugly closed,

the rib having an inclined end portion op- V posed to the rail end, enabling it to ride under and raise the rail, together with the burner support, when the cover is slightly open, to thereby provide clearance between the cover'and the burners and permittl -e freemovement of the mould.

3. A heating apparatus comprising a radially arranged fixed heater element, a

movable element adapted topass the heater elements, circumferentlal arcuate guard means operable to prevent the movable elenation of means, operable by the mould cover, when slightly raised, to elevate the support andthereby provide a clearance which permits the raised cover to pass under the burners, signalling means, and operating means therefor actuable by the cover in advance of the operation of the support elevating means.

Signed at the borough of Manhattan, in the city, county and State of New York, this 28th day of March, 1922.
